EMERSON G. COYEL, OF GLENS FALLS, NEV. YORK.

IMPROVEMENT I'N COMBINED WATER-WHEELS.

Speciiication forming part of Letters Patent No. 3,449, dated February 20, 1844.

, description thereof.

The water-wheel asA improved by me is divided horizontally into two section or partsanupper and a lower. One of these parts, usually the upper, is made fast to a vertical shaft, which shaft extends up from the water-wheelthrough a fiume or trunk, which is to contain the water. The two sections of the water-wheel are to revolve in reversed directions, the buckets which surround their peripheries being curved or inclined in such manner as to produce this eect.

In the accompanying drawings, Figure l is a perspective representation of my waterwheel, a portion of the iiurne being removed for the purpose of exhibiting it. Fig. 2 is a vertical section through the Hume and through the middle of the two sections of the wheels and of the gearing by which they are connected with each other. Fig 3 is a similar view to that given in Fig. l, but showing one section of the wheel only, with the buckets thereon simply inclined, instead of being curved, as in Fig. l.

A A is the tlume or trunk for containing the water.

B is the vertical shaft; O, the upper and D the lower section of the water-wheel.

E and F are curved buckets attached to the two sections of the water-wheel and as nearly touching the inner periphery of the fiume as may be. vEach of the sections has a solid head or plate c c c, extending from its periphery to its center'.

In Fig. 2 the gearing is shown by which the two sections of the wheel are connected together. The upper section O is supposed to be made fast to the shaftB, and the water acting upon it tends, of course, to turn said shaft. G is a bevel-wheel, which is also made fast to the shaft B, and Hwa similar wheel concentric with and made fast to the lower section D of the wheel. The shaft B passes through a collet or hole in the center of the section D and of the wheel H, so that this section andwheel would be loose upon the shaft, but for the gearing to be now described.

` I is an intermediate bevel-wheel gearing into the wheels G and H. The wheel I revolves freely on a center-pin or arbor a, which mextends out from and is made fast to a tube or collar J, through which the shaft B passes and within which it revolves, said collar remaining at rest. The outer end of the arbor ct is sustained by the upright h or in any other convenient way. Vhen the sections of the wheel are thus geared together, the power exerted upon them will be conveyed from one of them tothe other, and the change of direction given to the effluent Water will be found to economize the power communicated by it to a great extent. p

In constructing the buckets of my wheel I prefer to give to them a curvature such as is shown in Fig'. l; but this curvature may be changed or their form may be such aswill cause the descent of the water to be simply down an inclined plane, as shown in Fig. 3.

The curvature of the buckets E ofthe upper section of the wheel O resembles a Grecian cyma reversa and those lettered F of the lower section D a simple cavetto, arranged around the peripheries of the two sections of the wheel in such order as to gradually diminish thev size of the issues from the inletsto the outlets, causing the water after having acted by what is termed reaction on the concavoconvex surfaces of the buckets E in turning the section O of the wheel in the direction of the arrow No. l, Fig. l, to then strike against the concave sides of the buckets F of the lower section D and act by percussion and reaction to turn it in the direction of the arrow No. 2 or in a reverse direction, thus transmitting its power, with that of the upper section O, throughthe intervention of the gear if; i v3,449

ing` above described, to the shaft B, from which the power is conveyed wherever desired.

What I claim as my invention, and which I desire to secure by Letters Patent, s-

Combining the section C of the Water- Wheel, having cyniaJ reversa buckets E and contracted issues, with the section D, having concave or cavetto-shaped buckets F, the two sections being geared together by beve1-gear ing and turning in contrary directions in a, cyiindricai fiume by the reaction and percussion of t-he Water confined in said flume. as herein set forth.
